Mets starting pitcher Jeremy Hefner , who last month suffered a second UCL tear while attempting to return from the first, was examined by Dr. James Andrews Sunday and is likely headed for a second Tommy John surgery, according to ESPN.com.

"New CT scan and X-rays showed no healing," Hefner posted on Facebook. "Will continue to rest for a few more weeks. Surgery is likely, but not definite. Clarity will come soon."
